private int avoid

Mouse button that represents the popup trigger event.

active

private int active

Mouse button used to initiate the selection tracking.

Constructor Detail

SelectionTracker

public SelectionTracker(ChuiSimulator sim)

Construct an instance.

Parameters:

sim - The CHUI simulator for which selection tracking is done.

Method Detail

mousePressed

public void mousePressed(java.awt.event.MouseEvent evt)

Process a mouse button pressed event. If the button press is a popup trigger event, it is ignored. Otherwise, the button press starts a selection operation in the CHUI simulator. The button used to start the selection is saved off so that only events on that same button will affect the selection processing. The result of the selection operation is that the selected rectangle of text on the simulator's screen is identified (for copying to the clipboard) and a selection box is drawn around the selection area to give the user feedback on what exactly has been selected.

Specified by:

mousePressed in interface java.awt.event.MouseListener

Overrides:

mousePressed in class java.awt.event.MouseAdapter

Parameters:

evt - The mouse button event being processed.

mouseDragged

public void mouseDragged(java.awt.event.MouseEvent evt)

Process a mouse dragged event. If the mouse has been moved while the button is still pressed, a dragged event occurs. So long as this dragged event was generated while an active selection is underway, the selection rectangle in the CHUI simulator will be updated by this method.

Specified by:

mouseDragged in interface java.awt.event.MouseMotionListener

Overrides:

mouseDragged in class java.awt.event.MouseAdapter

Parameters:

evt - The mouse dragged event being processed.

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent evt)

Process a mouse button released event. If the button release is a popup trigger event, it is ignored. Otherwise, so long as a selection operation is in progress and the active selection button is the button that was released, this method will end the selection operation in the CHUI simulator. The selection at that point is final. The drawn box will not change, unless the selection is canceled by the user or a new selection operation starts.

Specified by:

mouseReleased in interface java.awt.event.MouseListener

Overrides:

mouseReleased in class java.awt.event.MouseAdapter

Parameters:

evt - The mouse button event being processed.
